It doesn't matter if it's 98 degrees of 15 degrees, if she sits for over a couple hours, she's super cold blooded. She'll pop right off, then die.. She'll start right back up again and idle kind of rough for a few minutes (literally) but then I can give her the beans a few times and she's good go! Runs like a champ the entire drive, every time. BUT! Just a bit groggy at cold start. I replaced the blue temp sensor hoping that was it, but nada. What do you all recommend? Any Ideas? Thank you in advance!

Did you check the wiring going to the sensor that was replaced? The wires under the boot of the connector were shorting on my car...
There is a guide on this forum for testing

I'd start by checking the DME temp sensor, AFM temp sensor and idle contact switch, all at the 35-pin DME connector (to root out harness issues and sensor issues). If those are all ok, I'd check the O2 sensor, and then spark strength.
